Contributors: M-Short

Overview

Do you have a bricked Arduino that won’t accept code anymore? Or, maybe you wrote your own firmware and would like to upload it to your Arduino? Or, maybe you just want to learn more about the inner-workings of Arduino, AVR, and microcontrollers in general. Well, you’re in luck! This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so.
